Description

Technical Field

[0001] This utility model relates to a connector, and more particularly to a shock-resistant high-current terminal. Background Technology

[0002] Existing high-current terminals for connecting PCBs and conductive boards typically use Figure 1 The structure shown is a rigid conductor terminal structure 7, with its lower solder feet soldered to the PCB and its upper part contacting and fixing to the conductive plate by a rivet nut.

[0003] When the high-current conductive terminal with the above structure is in use, if the conductive plate and PCB vibrate in the "Z" direction, multiple forces will be generated, and the fixing of the conductive terminal to the conductive plate and / or PCB will gradually loosen, resulting in poor contact. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a shock-resistant high-current terminal that can maintain reliable contact and fixation with the circuit board and conductive plate even under vibration environment.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a shock-resistant high-current terminal, including a terminal body and a rivet nut, wherein one end of the terminal body forms a welding end for welding to a circuit board, and the other end of the terminal body forms a conductive end. The rivet nut is riveted to the conductive end for fixing and connecting a conductive plate so that the conductive end of the terminal body contacts and conducts electricity with the conductive plate. The welding end and the conductive end of the terminal body are electrically connected through an elastic connection part that can generate elastic deformation under force.

[0006] As a further improvement of this utility model, the elastic connecting part is a cantilever structure formed by one bend or a tortuous structure formed by two or more back-and-forth bends.

[0007] As a further improvement of this utility model, the welding end and the conductive end of the terminal body are arranged in parallel and spaced apart, and the elastic connection part is accommodated in the gap between the welding end and the conductive end by repeatedly bending into a folded state. There is an elastic deformation clearance between adjacent bending edges of the elastic connection part.

[0008] As a further improvement of this utility model, the adjacent bent edges of the elastic connecting part form an acute angle greater than 0°, and the adjacent bent edges are connected by a circular arc structure.

[0009] As a further improvement of this utility model, the welding end of the terminal body includes a supporting plate and several welding feet, which are fixedly arranged at intervals on the peripheral side wall of the supporting plate.

[0010] As a further improvement of this utility model, a number of welding feet are symmetrically distributed on the support plate, and the center of gravity of the terminal body and the riveting nut on it is located at the center of symmetry of the welding feet.

[0011] As a further improvement of this utility model, the solder feet symmetrically distributed on both sides of the support plate are L-shaped or T-shaped structures with a root width greater than the end width, and the stepped surface between the two ends of the solder feet can stop on the surface of the circuit board.

[0012] As a further improvement of this utility model, the two ends of the elastic connecting part are integrally formed and fixedly connected to the side wall of the supporting plate and the plate-shaped conductive end, respectively. The two side walls of the supporting plate near the elastic connecting part are symmetrically bent to form supporting feet, which are supported on the surface of the circuit board.

[0013] As a further improvement of this utility model, the width of the elastic connecting part is smaller than the width of the supporting plate and the conductive end, and the two ends of the elastic connecting part form a connection structure with the width gradually increasing.

[0014] As a further improvement of this utility model, two rivet nuts are provided at intervals on the conductive end of the terminal body.

[0015] The beneficial effects of this utility model are as follows: The welding end and conductive end of the terminal body of this utility model are electrically connected through an elastic connection part that can produce elastic deformation under force, so that the terminal structure has good elasticity. Under vibration environment, most of the force in the "Z" direction will be absorbed by the elasticity of the terminal itself. The contact and fixation of the terminal to the circuit board and conductive plate are more reliable. The support plate of the welding end is provided with multiple support points. The center of gravity of the product is close to the center of several support points. Before the product is welded to the PCB, it can be placed stably on the PCB, which makes welding more convenient. Attached Figure Description

[0021] Example: A shock-resistant high-current terminal includes a terminal body and a rivet nut 1. One end of the terminal body forms a welding end for welding to a circuit board 8, and the other end of the terminal body forms a conductive end 3. The rivet nut 1 is riveted to the conductive end 3 for fixing and connecting a conductive plate 9 so that the conductive end 3 of the terminal body contacts and conducts electricity with the conductive plate 9. The welding end and the conductive end 3 of the terminal body are electrically connected through an elastic connection part 4 that can generate elastic deformation under force.

[0022] In use, the soldering end of the terminal body is soldered onto the circuit board 8, and the conductive end 3 of the terminal body is in flat contact with the conductive plate 9. The conductive end 3 of the terminal body and the conductive plate 9 are fixedly connected by the rivet nut 1 and screws. The conductive end 3 and the soldering end of the terminal body are arranged in the "Z" direction. By adding the elastic connection part 4, the terminal structure has better elasticity. Under vibration environment, most of the force in the "Z" direction will be absorbed by the elasticity of the terminal itself, and the contact and fixation of the terminal to the circuit board 8 and the conductive plate 9 are more reliable.

[0023] The elastic connecting part 4 is a cantilever structure formed by one bend or a tortuous structure formed by two or more bends. The elastic connecting part 4 can be formed by one bend or multiple bends, or it can be a spiral structure, as long as it forms an elastic structure in the "Z" direction.

[0024] The welding end and conductive end 3 of the terminal body are arranged parallel and spaced apart. The elastic connecting part 4 is accommodated in the gap between the welding end and the conductive end 3 by repeated bending. There is an elastic deformation clearance between adjacent bending edges of the elastic connecting part 4. The elastic connecting part 4 is located between the conductive end 3 and the welding end of the terminal body, saving space while providing elastic support for the conductive end 3.

[0025] The adjacent bent edges of the elastic connecting part 4 form an acute angle greater than 0°, and the adjacent bent edges are connected by a rounded structure. The bent edges of the elastic connecting part 4 are inclined, which makes them more elastic, and the rounded bends are stronger, making them less prone to breakage or damage during long-term use.

[0026] The welding end of the terminal body includes a supporting plate 2 and several welding feet 5, which are fixedly arranged at intervals on the peripheral sidewall of the supporting plate 2. The welding feet 5 are distributed on the outer peripheral sidewall of the supporting plate 2, which can achieve a stable connection with the circuit board 8 and provide more stable support for the conductive end 3, and can withstand greater pressure and torque.

[0027] Several solder feet 5 are symmetrically distributed on the support plate 2, and the center of gravity of the terminal body and its riveting nut 1 is located at the center of symmetry of the solder feet 5. The support plate of this structure is provided with multiple support points, and the center of gravity of the product is close to the center of several support points. Before the product is soldered to the PCB, it can be placed stably on the PCB.

[0028] The solder feet symmetrically distributed on both sides of the supporting plate 2 are L-shaped or T-shaped structures with a root width greater than the end width, and the stepped surface between the two ends of the solder feet can stop against the surface of the circuit board 8. This structure can ensure that the solder feet are welded at a consistent height.

[0029] The two ends of the elastic connecting part 4 are integrally formed and fixedly connected to the side wall of the supporting plate 2 and the flat conductive end 3, respectively. The supporting plate 2 has symmetrical bends on both side walls near the elastic connecting part 4 to form supporting feet 6, which support the surface of the circuit board 8. The supporting feet 6 provide support to the supporting plate and buffer the elastic deformation of the elastic connecting part 4.

[0030] The width of the elastic connecting part 4 is smaller than the width of the supporting plate 2 and the conductive end 3, and the two ends of the elastic connecting part 4 form a connection structure with the width gradually increasing.

[0031] Two rivet nuts 1 are spaced apart on the conductive end 3 of the terminal body. This improves the connection strength between the conductive end 3 of the terminal body and the conductive plate 9.
